This is a great quote from Timbaland. He as been very cocky in the past about JT etc, and to see how he really feels about MJ is awesome:
TIMBALAND: [Xscape] brought out a lot of emotions. It took me a week to get through it. Every time I would play a song I would be like, "Put on something else...I can't do this right now." But once I started getting into it and was at ease with it and prayed about it, the music started to come to me. And I'm going to be honest with you, listening to those raw tracks of Michael made me cry. He's not here to see this. So to hear him singing... man. I always tell people I don't care who you are and what you aspire to be. You will never be Michael Jackson. Usher is Usher. And Justin [Timberlake] is Justin. Those two guys are amazing. But there's no comparison to Michael Jackson. None.
